Starizona HyperStar 4 for Celestron C11 SCT with Filter Slider

The HyperStar C11 from Starizona has been designed to work with Celestron 11-inch Schmidt-Cassegrain telescopes. It helps capture up to a 3.7-degree field of view at an astonishing fast f/1.9! Cameras from Meade, Orion, Atik, SBIG, Mallincam, Starlight Xpress, etc. are perfect for the HyperStar C11. If your camera is not on the list, please write it into the field provided. It is also important that you give us your secondary housing and the mount style you plan to use with the Hyperstar. In this way, we can make sure you hit the ground running!

Based on Celestron's innovative Fastar feature, HyperStar by Starizona allows the secondary mirror on Celestron's Schmidt-Cassegrain telescopes to be removed. Mounting the HyperStar lens assembly in place of the secondary mirror enables you to mount a CCD camera at the front of the telescope. This provides much faster imaging and a wider field of view. Switching between HyperStar System to the telescope's normal f/10 configuration is simple, easy and requires no tools. No re-collimation is necessary because the telescope's secondary mirror is indexed.

This Starizona HyperStar Kit comes with the Filter Slider, which allows you to use multiple filters while imaging without removing the camera. Most filter wheels are too big to use with HyperStar; they block too much of the telescope’s aperture. The Starizona Filter Slider is built expressly for HyperStar imaging. It is only 0.69” thick and weighs just 5 ounces. The filter slider is round and smooth, with nothing to stick out and get in way of the light path. The HyperStar side of the filter holder has female M48 threads and the camera side has male T-threads. The included filter holder slides in and out of the filter slider body. Magnets hold the filter holder firmly in place yet allow easy filter change-out at any time. The included filter holder will hold 2” mounted filters with a standard 48 mm thread.
